AIIMS 2017 Biology Bryophytes MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Read the following statements regarding bryophytes and choose the incorrect option.

A

Gametophytic phase is dominant in life cycle

B

Fertilisation takes place in presence of water

C

Zygote undergoes meiosis to produce sporophyte

D

Sporophyte is physiologically dependent on gametophyte

Correct Answer

Option C

Detailed Explanation

In bryophytes, the zygote undergoes mitosis, not meiosis, to develop into the sporophyte, which is a diploid structure that remains attached to and dependent on the gametophyte for nutrition. Option A is correct as the gametophyte is the dominant phase of the life cycle, while option B is also accurate since fertilization requires water (H₂O) for sperm motility. Option D is true because the sporophyte relies on the gametophyte for sustenance, illustrating the interdependence of these two phases in bryophyte reproduction.
